You can't just say that the total carbon footprint of an electric vehicle is less than the equivalent gasoline version - it's not that simple. Here's an example, if the electricity needed to charge the batteries comes from wind or hydroelectric generation then, yes, the total carbon emmission (the "footprint") is going to be materially less. However, if that electricity comes from a coal fired plant in China with no scrubbers on the stacks then it's likely that total carbon emmissions will actually be roughly equal or even higher.
Generalizations in the environmental debate are difficult to make stand up because there are a lot of variables.
What we really need is a hydrogen fuel cell vehicle......zero emissions.....oh, wait, somehow we have to crack off hydrogen from somewhere, and that's not going to be a zero emission process....hhhhmmmm
